Answer:

Carrying capacity is defined a the ability of the natural ecosystem to take care of the environment which does not necessarily cause the resistance in population increase.

Explanation:

  • The earth indeed has a mechanism of delivering changes to the system and keeping it intact but as the case of the rapid growth of population arises the mother nature sees this as an exponent of unsustainable growth as the resource used to sustain large populations is no longer available or are exhausted.  
  • A population increase so does the carrying capacity and workload of the natural environment which at the time gets slow due either due to the man's artificial technology or the natural process like hurricane or earthquake itself.
  • But seeing the nature as providing possibilities for the existence of the societies throughout ages and hence trying to maintain its originality may break those activities that it considers resistance as several biotic factors like predators, disease, competition, and lack of food.

Why must zebras and wildebeests fill different niches on the open plains and woodlands of africa?
SCORPION-xisa [38]

The occupation of different niches on the open plains and woodlands of Africa by the zebras and the wildebeests is a result of niche partitioning. The zebras and the wildebeests in a common niche would compete for food, water, shelter, and space. This competition would affect the population growth of the two species by negatively affecting their reproductive capabilities. Thus, in the same habitat, the two species choose to occupy two different niches such that the competition between them is minimised. Hence they end up in separate niches.

Phenylketonuria, PKU, is a single-gene recessive human
astraxan [27]

Answer:

1/2

Explanation:

Let's assume that the allele "p" is responsible for PKU in the homozygous state. According to the given information, both the parents are unaffected by the disorder but have an affected child. This means that both the parents carry at least one copy of the recessive allele responsible for the disease. Therefore, the genotype of each of the parents is Pp. A cross between Pp and Pp would produce progeny in following ratio=

Pp x Pp = 1/4 PP: 1/2/ Pp: 1/4 pp

Therefore, the probability that their next child will carry just one recessive allele is 1/2.
